Summary of Financial Results

⁽¹⁾ This is a non-GAAP financial measure; see explanation and reconciliation of this non-GAAP financial measure to the most directly comparable GAAP financial measure below.

Three Months Ended September 30, 2021 Results

Revenue increased $21.0 million, or 33.3%, for the three months ended September 30, 2021 to $84.2 million as compared to $63.1 million for the three months ended September 30, 2020, primarily driven by an increase in remediation and compliance services revenue from the commencement of new project work, partially offset by a decrease in fossil services revenue due to project completions and a slight decrease in byproduct sales due to the dissolution of our Ash Venture LLC joint venture in the second quarter of 2021 and decreases in supply from international sources due to increases in shipping rates, partially offset by increased plant production as utility customers' production recovered from the impacts of the pandemic and the 2020 hurricanes. Gross profit increased $1.1 million, or 13.4%, for the three months ended September 30, 2021 to $9.4 million as compared to $8.3 million for the three months ended September 30, 2020, primarily driven by an increase in gross profit from our remediation and compliance services from the commencement of new project work, partially offset by a decrease in gross profit on our fossil services due to project completions and a decrease in gross profit on our byproduct sales due to the dissolution of our Ash Venture LLC joint venture in the second quarter of 2021. As a percentage of revenue, gross profit was 11.2% and 13.2% for the three months ended September 30, 2021 and 2020, respectively.

Net loss attributable to Charah Solutions, Inc. decreased $2.5 million, or 60.2%, for the three months ended September 30, 2021 to $1.7 million as compared to $4.2 million for the three months ended September 30, 2020. The decreased loss was primarily due to (i) a decrease in impairment expense, (ii) gains on sales of property and equipment, net of $3.0 million resulting from the commencement of operations at the Gibbons Creek ERT project in 2021 and the completion of an asset purchase agreement with a third party for the sale of certain grinding-related assets, (iii) a gain on ARO settlements of $1.1 million representing differences between the estimated costs used in the measurement of the fair value of the Company's AROs and the actual expenditures incurred for specific remediation tasks performed at the Gibbons Creek ERT project and (iv) the previously mentioned increase in gross profit. These favorable drivers were partially offset by a $7.1 million reduction in expense related to the expiration of our purchase option liability on our structural fill sites, which benefited 2020 but did not recur in 2021; other operating expenses from ERT services of $0.8 million resulting from the commencement of operations at the Gibbons Creek ERT project in 2021 and a decrease in income from equity method investment of $0.6 million resulting from the dissolution of our equity method investment joint venture in 2021.

Adjusted EBITDA ⁽¹⁾ increased $3.5 million, or 50.1%, to $10.4 million for the three months ended September 30, 2021 compared to $6.9 million for the three months ended September 30, 2020.

Nine Months Ended September 30, 2021 Results

Revenue increased $33.1 million, or 19.8%, for the nine months ended September 30, 2021 to $199.8 million as compared to $166.7 million for the nine months ended September 30, 2020, primarily driven by an increase in remediation and compliance services revenue from the commencement of new project work, partially offset by a decrease in byproduct sales and decrease in fossil services revenue due to project completions. The decrease in byproduct sales was primarily due to a decrease in supply from international sources due to increases in shipping rates, and the dissolution of our Ash Venture LLC joint venture in the second quarter of 2021, partially offset by increased plant production, as previously mentioned, and new ash sales sites. Gross profit increased $3.5 million, or 19.1%, for the nine months ended September 30, 2021 to $22.0 million as compared to $18.4 million for the nine months ended September 30, 2020, primarily driven by an increase in gross profit from our remediation and compliance services from the commencement of new project work, partially offset by a decrease in gross profit on byproduct sales due to the dissolution of our Ash Venture LLC joint venture in the second quarter of 2021 and a decrease in gross profit on our fossil services due to project completions. As a percentage of revenue, gross profit was 11.0% and 11.1% for the nine months ended September 30, 2021 and 2020, respectively.

Net loss attributable to Charah Solutions, Inc. decreased $14.9 million, or 67.6%, for the nine months ended September 30, 2021 to $7.1 million as compared to $22.0 million for the nine months ended September 30, 2020. The decreased loss was primarily due to (i) the decrease in loss on extinguishment of debt resulting from the absence of $8.6 million of expenses incurred as a result of the Company's Amendment No. 3 to Credit Agreement of our existing Credit Facility during the nine months ended September 30, 2020, (ii) gains on sales of property and equipment, net and other operating income from ERT services of $6.2 million resulting from the commencement of operations at the Gibbons Creek ERT project in 2021 and the completion of an asset purchase agreement with a third party for the sale of certain grinding-related assets, (iii) a decrease in impairment expense, (iv) a gain on a sales-type lease of $5.6 million for an ERT project recognized during the nine months ended September 30, 2021, (v) the previously mentioned increase in gross profit and (vi) a gain on ARO settlements of $1.1 million representing differences between the estimated costs used in the measurement of the fair value of the Company's AROs and the actual expenditures incurred for specific remediation tasks performed at the Gibbons Creek ERT project. These favorable drivers were partially offset by a $7.1 million reduction in expense related to the expiration of our purchase option liability on our structural fill sites, which benefited 2020 but did not recur in 2021; the absence of income from discontinued operations, net of tax of $6.9 million during the nine months ended September 30, 2021 due to the Company's sale of its Allied subsidiary in November 2020; other operating expenses from ERT services of $2.1 million during the nine months ended September 30, 2021, and a decrease in income from equity method investment of $1.1 million resulting from the dissolution of our equity method investment joint venture in 2021.

Adjusted EBITDA ⁽¹⁾ increased $13.8 million, or 109.6%, to $26.4 million for the nine months ended September 30, 2021 compared to $12.6 million for the nine months ended September 30, 2020.

Business Developments

New Business Awards

To date in 2021, we have won $805 million of new awards, including approximately $120 million awarded since our second quarter 2021 earnings release in August. Although the timing of new business awards is not within our control, based on our assessment of our competitive position with respect to pending bids, we expect that new business awards for the full year will exceed the year-to-date level of $805 million.

The most recent awards included two ash pond closure contracts and an ash pond stabilization contract with a longstanding Southeastern utility customer. We also were awarded a five-year byproduct sales and marketing contract with Associated Electric Cooperative for 150,000 tons annually of fly ash, bottom ash and boiler slag from the Thomas Hill Energy Center and a five-year contract with the Gavin Power Plant for 35,000 to 60,000 tons annually of fly ash. Under both contracts, we will be responsible for the environmentally friendly recycling of these byproducts and marketing of them for use in ready-mix concrete as an economic replacement for Portland cement. We will be targeting regional markets using our MultiSource® materials network for distribution.

ERT Services

We continue to evaluate opportunities to leverage our innovative and sustainable ERT solutions further to meet the evolving and increasingly complex needs of utilities and power generation companies as they seek to retire and decommission older or less economically viable generating assets while minimizing costs and maximizing the value of the assets and improving the environment. Our unique ability to provide a single-source solution for large-scale, complex environmental challenges continues to position us as a strong partner for existing and potential new customers. We are very pleased with our performance at our ongoing ERT projects, and we continue to believe that Charah Solutions possesses unique competitive advantages and benefits for our utility customers compared to other alternatives.

Gibbons Creek : We achieved a major milestone by completing the planned implosion and demolition of the plant in October. Remediation efforts at the project continue to progress on plan and below budget. We expect remediation of the ash and scrubber ponds to be substantially complete by year end with remediation work on the landfill still to be performed as planned. With demolition completed, we expect scrap sales to accelerate in the fourth quarter and continue into 2022. We are nearing completion on parcel redevelopment for the site, and expect to see parcel sales accelerating in early 2022.

B.C. Cobb: This project for Consumers Energy involved remediation of the existing ash ponds and repurposing of the site to natural wetlands along the shore of Lake Michigan. Work is progressing well and is expected to be substantially completed by year end.

Avon Lake : We expect to close on the acquisition of the Avon Lake Generating Station and adjacent property from GenOn in April 2022, when the plant ceases operation. We have commenced planning for the environmental remediation and sustainable redevelopment of the property and will begin physical work once the full transfer occurs. We have retained a third party to provide real estate advisory, development, and brokerage services to oversee the redevelopment of the property in an environmentally conscious manner and future sale of the remediated property. We are working with the local community to position the property to expand economic activity and benefit the surrounding area through job creation.

Remediation and Compliance

Work is progressing well on several previously announced large remediation projects, including a coal ash reclamation project for Dominion Energy and two long-term ash pond closure-by-removal projects for another longstanding Southeastern utility customer. The projects are on schedule and on budget. The first phase of the Dominion project is expected to be substantially completed by year end with an expected ramp of the second phase beginning in 2022. We also began work on three new ash pond remediation contracts that were awarded recently by the above-referenced large Southeastern utility customer.

Byproduct Sales

Byproduct sales decreased in the first half of this year, likely attributable to the impact of the COVID-19 pandemic on power generation levels and construction activity, as well as a change in the sales mix. However, the third quarter 2021 level was approximately level with a year ago and showed sequential improvement from the first two quarters of this year. As the economy continues its recovery, we expect to see continued sequential improvement in byproduct sales, although the full year 2021 result is likely to be below the level of 2020, primarily due to a change in sales mix. Recently enacted infrastructure legislation is expected to be beneficial to this business over a multiyear period with an expected increase in demand for concrete.

ESG Reporting

During the first quarter of 2021, we issued our first annual ESG Report to showcase Charah Solutions' significant leadership in fulfilling our ESG commitments and sustainably preserving our natural resources for the betterment of our planet, our communities, and our customers. Through our various businesses, we reduce greenhouse gas emissions, decrease landfill disposal, remediate land for community and business use, conserve natural resources, and protect our waterways. Our ERT business provides innovative, environmentally-conscious solutions to utilities and power generation companies seeking to decommission older or less economically viable generating plants and communities seeking to ensure that redevelopment of the property brings economic benefits to the area. Our EnviroSource^™ technology offers resource conservation and recovery through the beneficial recycling of coal ash into a product that can substitute for Portland cement. Our remediation and compliance business ensures the secure closure of ash impoundment facilities.

In our initial ESG report, we laid out 2021 objectives in the key areas of Environmental, Data Acquisition and Reporting Capabilities, Diversity and Inclusion, and Safety. We are on track or ahead of plan with respect to these goals. In the area of Safety, for example, our Total Recordable Incident Rate for 2021 to date was 0.22, significantly better than our goal of 0.46 or better (lower). We have had zero lost time injuries this year to date.

During the third quarter, we were recognized as a leader in construction safety for the fourth year in a row by the Annual Associated General Contractors of America. We also received seven employee safety awards from the North Carolina Department of Labor for our outstanding record of employee safety in 2020, the ninth year that we have been recognized for our safety record.

Financing Activities

Stock Purchase Agreement

On August 6, 2021, we executed a stock purchase agreement with B. Riley Financial, under which we issued approximately 2.9 million shares of common stock at $4.50 per share in a private placement, for total proceeds of $13 million.

Senior Notes Issuance

On August 25, 2021, we issued $135.0 million of 8.50% unsecured senior notes (the "Notes") with a maturity date of August 31, 2026. Net proceeds to us after debt issuance costs were $123.1 million. We used the net proceeds from this offering and the proceeds from our equity issuance to B. Riley to repay all loans and borrowings outstanding under our Credit Facility and Revolver, which totaled $126.5 million. Following this repayment, the Credit Facility was terminated. The letters of credit outstanding under the Revolver at termination were cash collateralized with the proceeds from a $17.9 million promissory note we issued to B. Riley on August 25, 2021.

This refinancing provides us with greater financial flexibility relative to the Credit Facility as the Notes do not have financial covenants. Thus, we will not be required to comply with net leverage and fixed charge coverage ratios on a quarterly basis as we were under our previous Credit Facility. In addition, the Notes are bullet maturities and thus do not require amortization of principal prior to maturity, unlike the Credit Facility. Interest expense on the Notes is comparable the level we incurred on the Credit Facility, but cash used for debt service is lower on the Notes as there is no amortization of principal. With a 2026 maturity date, the Notes improve our maturity profile relative to the Credit Facility, which would have matured in 2022.

New Credit Agreement

On November 9, 2021, we closed on a new credit agreement with JPMorgan Chase Bank, N.A. The credit agreement provides for a four-year senior secured revolving credit facility of up to $30 million, plus an additional $5 million of capacity that is available for letters of credit which are supported by cash collateral provided by the Company. Availability under the Credit Agreement is subject to a borrowing base calculated based on the value of certain eligible inventory, accounts receivable and equipment of the Company. We are not subject to any financial covenants under the new facility unless available liquidity falls below a minimum level, in which case we would be required to ensure that the Fixed Charge Coverage Ratio (as defined in the Credit Agreement) is not less than 1.00 to 1.00. In keeping with our strong ESG focus, we were invited to participate in JPMorgan's sustainability-linked pricing structure. Under this innovative incentive, Charah Solutions will receive facility fee and interest rate reductions from JPMorgan based on meeting certain ESG metrics as defined by the Company and consistent with the one- and five-year goals in our inaugural ESG Report issued earlier this year. We do not expect to draw under the new facility. We do expect to reissue and replace existing letters of credit under the new facility. Upon reissuance and cancellation of the existing letters of credit, the cash collateral securing the existing letters of credit will be released and will be used to repay the $17.9 million promissory note to B. Riley in full.

2021 Guidance

We provide mission-critical services to a diversified base of customers, a majority of whom are investment-grade regulated utilities that must continue to operate their power plants reliably despite the challenges presented by the COVID-19 pandemic. To date we have not experienced any significant disruptions to our business due to the pandemic. However, the ongoing pandemic and potential for significant business disruptions beyond our control have created a high level of uncertainty, including but not limited to the potential impacts on demand-driven power generation and the level of construction activity (each of which affects our byproduct sales). There are also timing uncertainties associated with the startup of recently announced customer awards, including ERT awards. Unfavorable weather, including hurricanes, excessive rain or moderate temperatures (which may temper power generation and therefore ash production levels), could adversely affect results at any or all of our businesses.

Results for the fourth quarter of this year should benefit from an increased contribution from our Gibbons Creek ERT project and the continued ramping of recent new awards, including large remediation and compliance projects.

Based on our results year to date and our current expectations for the fourth quarter of the year, we now expect to be in the upper half of our initial 2021 guidance ranges for revenues, Adjusted EBITDA ⁽²⁾ and Adjusted free cash flow ⁽²⁾ and have narrowed these ranges as follows:

• Revenues of $280million to $300 million (previously $260 million to $300 million)
• Net loss attributable to Charah Solutions, Inc. of $5 million to $0 million (unchanged)
• Adjusted EBITDA ⁽²⁾ of $37 million to $40 million (previously $35 million to $40 million)
• Adjusted free cash flow ⁽²⁾ of $35 million to $38 million (previously $33 million to $38 million)

This guidance is based on our current expectations of no material worsening of the COVID-19 pandemic, specifically including, but not limited to, no material customer work stoppages, no significant employee absences, no government-mandated quarantines and no material worsening of supply chain issues that could potentially affect our byproduct sales revenue. Any worsening of the COVID-19 pandemic could materially affect our 2021 outlook. This guidance also assumes that we do not experience material adverse weather in the fourth quarter of 2021.

⁽²⁾ The forward-looking measures of 2021 Adjusted EBITDA and Adjusted free cash flow are non-GAAP financial measures that cannot be reconciled to net loss attributable to Charah Solutions, Inc. and cash flows from operating activities, respectively, as the most directly comparable GAAP financial measure without unreasonable effort primarily because of the uncertainties involved in estimating forward-looking measures.

Non-GAAP Reconciliation: Net Loss Attributable to Charah Solutions, Inc. to Adjusted EBITDA
(in thousands)
(Unaudited)

We define Adjusted EBITDA as net loss attributable to Charah Solutions, Inc. before income from discontinued operations, net of tax, interest expense, net, loss on extinguishment of debt, income taxes, depreciation and amortization, equity-based compensation, impairment expense and transaction-related expenses and other items. Adjusted EBITDA margin represents the ratio of Adjusted EBITDA to total revenue. We believe Adjusted EBITDA and Adjusted EBITDA margin are useful performance measures because they allow for an effective evaluation of our operating performance compared to our peers, without regard to our financing methods or capital structure.

The following table presents a reconciliation of Adjusted EBITDA to net loss attributable to Charah Solutions, Inc., our most directly comparable financial measure calculated and presented in accordance with GAAP, along with our Adjusted EBITDA margin.

⁽¹⁾ Represents amounts for continuing operations only.

⁽²⁾ Represents expenses associated with the Amendment to the Credit Facility and other miscellaneous items. Negative amounts represent settlement recoveries related to these matters.

⁽³⁾ Adjusted EBITDA margin is a non-GAAP financial measure that represents the ratio of Adjusted EBITDA to total revenue. We use Adjusted EBITDA margin to measure the success of our businesses in managing our cost base and improving profitability.

Non-GAAP Reconciliation: Net Loss Attributable to Common Stockholders to
Adjusted Net Loss Attributable to Common Stockholders and Adjusted Loss per Basic/Diluted Share
(in thousands, except per share data)
(Unaudited)

Adjusted net loss attributable to common stockholders and Adjusted loss per basic/diluted share are non-GAAP financial measures. We define Adjusted net loss attributable to common stockholders as net loss attributable to common stockholders less, on a post-tax basis, income from discontinued operations, net of tax and plus, on a post-tax basis, loss on extinguishment of debt, impairment expense and transaction-related expenses and other items. Adjusted loss per basic/diluted share is based on Adjusted net loss attributable to common stockholders.

The following represents a reconciliation of net loss attributable to common stockholders, our most directly comparable financial measure calculated and presented in accordance with GAAP, to Adjusted net loss attributable to common stockholders and Adjusted loss per basic/diluted share.

⁽¹⁾ Represents amounts for continuing operations only.

⁽²⁾ Represents expenses associated with the Amendment to the Credit Facility and other miscellaneous items. Negative amounts represent settlement recoveries related to these matters.

⁽³⁾ Represents the effective tax rate of (13.4)% and 27.3% for the three months ended September 30, 2021 and 2020, respectively, and (6.5)% and (2.2)% for the nine months ended September 30, 2021 and 2020, respectively, multiplied by adjusted (loss) income before income taxes attributable to common stockholders.

⁽⁴⁾ As a result of the loss per share for the three months ended September 30, 2021 and nine months ended September 30, 2021 and 2020, the inclusion of all potentially dilutive shares would be anti-dilutive. Therefore, dilutive shares of 12,379 were excluded from the computation of the weighted-average shares for diluted net loss per share for the three months ended September 30, 2021, and dilutive shares of 12,064 and 8,292 were excluded from the computation of the weighted-average shares for diluted net loss per share for the nine months ended September 30, 2021 and 2020, respectively.
